RESUMO

Superior vena cava syndrome (SVCS) often relates to malignant causes such as lung tumors, metastatic cancer, or lymphomas. While the diagnosis relies nowadays on the use of contrast-enhanced thoracic computed tomography, ultrasonography may have an important value as a first-line imaging technique, particularly when used in point-of-care office-based settings. Here, we report the case of a 67-year-old male presenting with SVCS in whom ultrasound contributed to diagnosis.

RESUMO

The advent of the autonomous car is paving the road to the realization of ideas that will help optimize traffic flows, increase safety and reduce fuel consumption, among other advantages. We present one proposal to bring together Virtual Traffics Lights (VTLs) and platooning in urban scenarios, leaning on vehicle-to-vehicle (V2V) communication protocols that turn intersections into virtual containers of data. Newly-introduced protocols for the combined management of VTLs and platoons are validated by simulation, comparing a range of routing protocols for the vehicular networks with the baseline given by common deployments of traditional traffic lights ruled by state-of-the-art policies. The simulation results show that the combination of VTLs and platoons can achieve significant reductions in travel times and fuel consumption, provided that proper algorithms are used to handle the V2V communications.

RESUMO

Breeding for dry matter yield and persistence in alfalfa (Medicago sativa L.) can take several years as these traits must be evaluated under multiple harvests. Therefore, genotype-by-harvest interaction should be incorporated into genomic prediction models to explore genotypes' adaptability and stability. In this study, we investigated how enviromics could help to predict the genotypic performance under multiharvest alfalfa breeding trials by evaluating 177 families across 11 harvests under four cross-validation scenarios. All scenarios were analyzed using six models in a Bayesian mixed model framework. Our results demonstrate that models accounting to the enviromics information led to an increase of genetic variance and a decrease in the error variance, indicating better biological explanation when the enviromic information was incorporated. Furthermore, models that accounted for enviromic data led to higher predictive ability (PA) in a reduced number of harvests used in the training data set. The best enviromic models (M2 and M3) outperformed the base model (GBLUP model-M0) for predicting adaptability and persistence across all cross-validation scenarios. Incorporating environmental covariates also provided higher PA for persistence compared with the base model, as predictions increased from 0 to 0.16, 0.20, 0.56, and 0.46 for CV00, CV1, CV0, and CV2. The results also demonstrate that GBLUP without enviromics term has low power to predict persistence, thus the adoption of enviromics is a cheap and efficient alternative to increase accuracy and biological meaning.

RESUMO

BACKGROUND: Major colorectal surgery usually requires a hospital stay of more than 12 days. Inadequate pain management, intestinal dysfunction and immobilisation are the main factors associated with delay in recovery. The present work assesses the short and medium term results achieved by an enhanced recovery program based on previously published protocols. METHODS: This prospective study, performed at 12 Spanish hospitals in 2008 and 2009, involved 300 patients. All patients underwent elective colorectal resection for cancer following an enhanced recovery program. The main elements of this program were: preoperative advice, no colon preparation, provision of carbohydrate-rich drinks one day prior and on the morning of surgery, goal directed fluid administration, body temperature control during surgery, avoiding drainages and nasogastric tubes, early mobilisation, and the taking of oral fluids in the early postoperative period. Perioperative morbidity and mortality data were collected and the length of hospital stay and protocol compliance recorded. RESULTS: The median age of the patients was 68 years. Fifty-two % of the patients were women. The distribution of patients by ASA class was: I 10%, II 50% and III 40%. Sixty-four % of interventions were laparoscopic; 15% required conversion to laparotomy. The majority of patients underwent sigmoidectomy or right hemicolectomy. The overall compliance to protocol was approximately 65%, but varied widely in its different components. The median length of postoperative hospital stay was 6 days. Some 3% of patients were readmitted to hospital after discharge; some 7% required repeat surgery during their initial hospitalisation or after readmission. The most common complications were surgical (24%), followed by septic (11%) or other medical complications (10%). Three patients (1%) died during follow-up. Some 31% of patients suffered symptoms that delayed their discharge, the most common being vomiting or nausea (12%), dyspnoea (7%) and fever (5%). CONCLUSION: The following of this enhanced recovery program posed no risk to patients in terms of morbidity, mortality and shortened the length of their hospital stay. Overall compliance to protocol was 65%. The following of this program was of benefit to patients and reduces costs by shortening the length of hospital stay. The implantation of such programmes is therefore highly recommended.

RESUMO

Contexto: Al momento existen pocos datos científicos que comparen las tres modalidades de tratamiento en Hiperplasia Prostática Benigna para determinar el mejor resultado clínico, considerando que se trata de una patología cuya incidencia aumenta a medida que aumenta la esperanza de vida poblacional. Objetivo: Comparar los resultados clínicos entre el tratamiento inicial farmacológico, no farmacológico y quirúrgico, basándose en la clínica de prostatismo en pacientes con Hiperplasia Prostática Benigna durante el período de enero 2014 a diciembre 2016. Diseño: Estudio Observacional, tipo Cohorte Retrospectiva. Pacientes y Métodos: Se procedió a dividir a 399 pacientes de acuerdo a la modalidad de tratamiento recibida. Se comparó la disminución del cuadro clínico en la primera consulta postratamiento utilizando una matriz de evaluación de síntomas urinarios elaborada por los autores, basada en la escala IPSS, que estratificó a los pacientes por el grado de severidad de la sintomatología. Se utilizó el software SPSS®. Resultados: Dentro del tratamiento no farmacológico, existió una diferencia de medias de 1,67 (IC 95% 0,49 ­ 2,85, p < 0,05); para el farmacológico fue de 0,21 (IC 95% 0,92 ­ 1,34, p = 0,713) y para el quirúrgico fue de 8,23 (IC 95% 7,19 ­ 9,27, p < 0,05). Se encontraron diferencias significativas entre los tres grupos durante la fase pretratamiento, tras estratificarlos de acuerdo al grado de severidad. Post- intervención, se compararon los resultados clínicos de cada tratamiento hallando que en pacientes con síntomas leves no existieron diferencias significativas (p = 0,087), no así para pacientes con sintomatología moderada y severa en donde se encontró una diferencia estadísticamente significativa. Conclusión: En pacientes con sintomatología urinaria catalogada como moderada y severa dentro de esta muestra, el tratamiento quirúrgico disminuyó la sintomatología urinaria en mayor proporción en comparación con el tratamiento farmacológico y el no farmacológico


Background: Currently there are few scientific data comparing the three therapeutic modalities of Benign Prostatic Hyperplasia to determine the best clinical outcome, considering that it is a pathology whose incidence increases as population life expectancy arise. Objectives: To compare the clinical results between the initial pharmacological, nonpharmacological and surgical treatment, based on clinical signs of prostatism in patients with benign prostatic hyperplasia during the period between January 2014 and December 2016. Study Design: Retrospective Cohort Study. Methods: 399 patients were divided according to the modality of treatment received: nonpharmacological, pharmacological and surgical. The decrease of the symptoms was compared with the first post-treatment consultation by using a matrix of evaluation of urinary symptoms elaborated by the authors, based on SPSS International Score; this tool stratified the patients by the severity of the symptomatology. SPSS® software was used. Results: Within the non-pharmacological treatment, there was a mean difference of 1.67 (95% CI 0.49 - 2.85, p <0.05); for the pharmacological it was 0.21 (95% CI 0.92 - 1.34, p = 0.713) and for the surgical was 8.23 (95% CI 7.19 - 9.27, p <0.05). Significant differences were found between the three groups during the pretreatment phase, after stratifying them according to the degree of severity. Post-intervention, the clinical results of each treatment were compared, finding that in patients with mild symptoms there were no significant differences (p = 0.087), not so for patients with moderate and severe symptoms where a statistically significant difference was found. Conclusion: In patients with urinary symptoms classified as moderate and severe within this sample, surgical treatment decreased urinary symptomatology in greater proportion compared to pharmacological and non-pharmacological treatment

RESUMO

OBJECTIVE: To describe the different ultrasound (US) findings of mature testicular hamartomas in children. MATERIALS AND METHODS: This is a retrospective study from January 2000 to July 2012 that reviewed the clinical, laboratory, and US findings of 7 children with a pathologic diagnosis of mature teratoma of the testis. All patients in the study received surgery (tumorectomy or orchiectomy), and the material was examined by the institution's Pathology Department. RESULTS: The US findings were varied and distinct. As to the lesions' consistency, they were cystic (n: 1), multicystic (n: 2), solid-cystic (n: 1), solid containing larger or smaller calcifications (n: 2), and focal calcification (n: 1). With regard to total circulation, all the solid lesions had few vessels in the interior of the lesions. CONCLUSION: Testicular teratoma has a very variable US appearance and can simulate that of other lesions. It can be single, multiseptated, small, or large. It can contain diffuse or localized calcifications. The testicle can have an increased or a normal volume.

RESUMO

Neste estudo aplicamos o questionário CAGE a 432 pacientes internados num hospital geral universitário, no dia de sua internaçäo. No período de 24 a 32 horas após a internaçäo, os pacientes com este CAGE positivo e seus controles pareados CAGE negativos foram submetidos a um exame psiquiátrico para avaliaçäo de sintomas sugestivos de síndrome de abstinência, preenchendo-se a escala CIWA-A. Os resultados sugerem uma pequena especificidade do questionário CAGE para síndrome de abstinência grave; porém, este instrumento mostrou-se eficaz na detecçäo de pacientes com síndrome de grau leve
